Katherine Jenkins said: "It was wonderful to be involved in a project celebrating such a great Welshman. It's also been such a joy to collaborate with so many other welsh artists whom I respect and admire. I hope the results are a fitting tribute."

Meanwhile, executive producer Bethan Jones said: "It's been an enormous privilege to work with such an extraordinary ensemble of Welsh talent for this unique presentation of Dylan Thomas' play, and an amazing experience to witness how this familiar text feels fresh and alive when read with truth and simplicity by this wonderful cast.

"It's almost as though this material is part of everyone's DNA. Our starting point was Dylan's only note to the original cast before the very first performance in New York shortly after he completed the play - 'Love the words'."

The stars will take part from various locations across the world, including Laugharne and New York City.

Under Milk Wood was written over a 10 year period in Laugharne and in New York, where it had its first performance in 1953.
